What is Liquid Chlorophyll?

Liquid Chlorophyll (Chlorophyllin (sodium copper chlorophyllin)) is a debunked supplement marketed for no credible human evidence supports the viral marketing claims (detox, alkalizing, boosting energy, or 'cleansing the blood'). NutriDex grades the human evidence as No Evidence. Liquid chlorophyll products are typically sodium copper chlorophyllin, a water-soluble derivative of plant chlorophyll long used as a food coloring and an over-the-counter 'internal deodorant.' Social-media claims that drinking it detoxifies the body, clears acne, deodorizes, alkalizes the blood, or boosts energy have essentially no credible human evidence; the most thorough systematic review found efficacy data weak and largely confined to topical or niche uses. The strongest human trial data are off-label: oral chlorophyllin lowered a urinary aflatoxin-DNA adduct biomarker by about 55% in adults at high liver-cancer risk in Qidong, China, and a small pharmacokinetic study suggested it can reduce aflatoxin absorption — findings specific to carcinogen exposure, not everyday wellness. Acne improvement has been shown only for a topical 0.1% copper-chlorophyllin gel in a 10-person pilot, not for the drinkable form. It is generally well tolerated, with harmless green discoloration of urine/stool, occasional GI upset, and a risk of photosensitivity. Overall, for its viral marketed claims the human evidence is best described as none.

Marketed Claims (unproven)

✕No credible human evidence supports the viral marketing claims (detox, alkalizing, boosting energy, or 'cleansing the blood')
✕Internal-deodorant use (body/fecal odor) is FDA-permitted historically but rests on thin, poorly-controlled mid-20th-century data; modern rigorous trials have not confirmed a benefit in healthy people
✕Acne/skin-clearing claims for oral chlorophyll are unsupported; the only positive acne data come from a tiny TOPICAL copper-chlorophyllin pilot, not from drinking it
✕Oral chlorophyllin has reduced an aflatoxin-DNA damage biomarker in a high-exposure population in China — a narrow chemoprevention context, not a wellness benefit for the general public
✕Plausible but unproven antioxidant activity; human data are limited and do not translate into the marketed health outcomes

Dosing & Compounds

Use & Legality
Commonly marketed at ~100–300 mg/day of chlorophyllin copper complex (e.g., 100 mg up to 3x/day); historical FDA internal-deodorant ceiling is 300 mg/day. No dose is established to deliver the advertised 'detox' or wellness effects.
Active Compounds
Sodium copper chlorophyllin (water-soluble semi-synthetic chlorophyll derivative)Chlorin e4 and chlorin e6 ethyl esters (principal active components)Copper-chelated porphyrin ringPheophorbide (a photoactive breakdown metabolite, relevant to photosensitivity)

Safety & Cautions

Generally well tolerated at typical doses. Common, harmless effects include green discoloration of urine, stool, or tongue. Doses above ~300 mg/day commonly cause GI upset — diarrhea, cramping, excess gas, and occasional nausea. Photosensitivity is a recognized risk: chlorophyll breakdown yields photoactive pheophorbides, so users should apply sun protection, and people taking other photosensitizing drugs (certain antibiotics, retinoids, St. John's Wort) or undergoing phototherapy should be cautious. The copper in copper chlorophyllin is a consideration for anyone with Wilson's disease or copper-overload conditions. Safety has not been established in pregnancy or breastfeeding, so these groups should avoid it. People with liver or kidney disease, and children, should consult a clinician first. Because chlorophyllin may bind compounds in the gut, separate it from oral medications by a couple of hours to avoid reduced absorption. Liquid products vary widely in concentration and purity (a dietary supplement, not a regulated drug); it is not a substitute for medical detoxification or any prescribed treatment. Educational only — always check with your doctor or pharmacist before combining Liquid Chlorophyll with any medicine.

Evidence & Risk Findings ★ 11 studies

Systematic review Systematic review ✓ PubMed
The Natural Standard evidence-based review of chlorophyll/chlorophyllin graded the supporting clinical evidence as generally weak across claimed uses, finding insufficient rigorous human data for detoxification, deodorizing, or systemic health benefits.

Regulatory monograph Regulatory record ✓ Source
FDA historically permits chlorophyllin copper complex as an OTC internal deodorant up to 300 mg/day with no reported adverse effects at that dose, but the underlying odor-reduction efficacy data are old and poorly controlled.
Safety / toxicology Naunyn-Schmiedeberg Arch Pharmacol 2025 ✓ Source
Preclinical safety/pharmacokinetic evaluation found oral sodium copper chlorophyllin well tolerated up to 5000 mg/kg in acute toxicity studies with no signs of toxicity or death, and explored efficacy in breast cancer chemotherapy and cyclophosphamide-induced bladder toxicity.
